Yeah, I never actually see any roots running underground. That's why I don't deal with it. I assume they must be really deep, and I would have to dig up the entire garden to get to them!

I remember the blackberries of the northwest! We would go to thickets to pick them and I remember being completely freaked out by the spiders that loved to nest in them. My parents made do on a very small income with five kids, and so we went everything-picking... blackberries, strawberries, apples, etc. All of it was processed into jam or canned preserves or put in the freezer. But yeah, those blackberry vines can take over everything if they aren't hacked back!
